C.F.BATH LIFTING JACK Filed Nov. 1, 1927 Patente-cly Sept. 17, 1929UNITED STATESL CHRISTIAN F. BATH, or ABILENEKANSAS LIFTING JACKApplication filed November 1, 1927. Serial No. 280,362.y f

The present invention is directed to improvements in lifting jacks.

The primary object of the invention is to provide a. device of thischaracter constructed in such manner that a piano or other article offurniture can be lifted in order that floor coverings may be placedthereunder.

Another object of the invention is to provide al device of this typewhich is simple in construction, durable, efficient in' operation andone which can be manufactured at a very small cost.

Another object of the invention is to provide a jack for this purposewhich can be operated with very little effort on the part of the userand held in its operative position with ease, while the floor coveringis being properly placed thereunder.

With these and other objects in view, this invention resides in thenovel features of construction, formation, combination and arrangementof parts to be hereinafter more fully described, claimed and illustratedin the accompanying drawing, in which- Figure 1. is a side elevationthereof.

Figure 2 is a view partly in elevation and partly in section.

Figure 3 is a sectional view on line 3-3 of Figure 2.

Figure 4 is a fragmentary detail vertical sectional view.

Referring to the drawing, 1 designates a base plate and 2 a pedestal,said pedestal being formed from a single strap of metal so bent as toprovide spaced sides 3-3 connected at their upper ends by a top 4 havinga slot 5 formed therein, the purpose of which will be later explainedThe lower ends of the sides 3 terminate in horizontal flanges 5 whichare secured to the base plate 1 by rivets 6.

The lifting bar 6 includes a vertically disposed shank 7 capable ofsliding in the slot 5, said shank having its lower end provided with ahorizontall disposedy extension 8` upon which is welc ed a foot plate 9.The shank 7 is provided with a vertical slot 10 for slidablyengaging thecross bolt 11 sup'- ported by the sides 3-,3,'said bolt serving to guidethe lifting bar during the movement thereof. They shank has fixedthereto a purpose fof which will be 'It will be obvious that when thelever 15 is swung downwardly the lifting bark 6 andy the foot plate 9will be elevated owing to the fact that the inner end of the leverengages the lug 12, and upon placing the foot plate 9 under a piano orother article the same can be conveniently lifted,

Upon reference to Figure 4 it will be oby served that the shank 7 liesadjacent one of the sides 3 and the slot 5 is offset to accommodate saidshank. n

From the foregoing description itwill be' seen that a jack has beenprovided which is extremely simple in construction and one which can beeasily and quickly kplaced in a l rposition to permit the foot plate9 toengage under the article to be lifted, the construc- 'y tion beingsuchthat very little effort will be' required to elevate the lifting barand foot plate. Having thus `described the invention, Ik n s 85.
